outer or projected position by a tension spring 13 (Figure 2) the inner end of Which is secured to pin l1, the outer end ot this spring being secured to a bracket 14 suitably secured to the inner face of the frontwall of the casing. i

The plunger or sli-de 12 operates in a supporting and guide bracket 15 otchannel cross section secured to the outer tace of the front Wall ot the casing, this bracket being aligned With a slot through front Wall 1a of the casing through Which the plunger operates. The plunger is provided with an outer thickened portion 12a` Vforming a shoulder` 16. `The plunger is cut away from the edge thereof Which is directed toward the associated operating head -5 to providean arcuate cut or recess 17 Which corresponds lin radius to the radius of the cointo be used Withthe selected plunger. l

Referring more particularly to Figures 5 and 6, head 5 is provided with a straight vedge 50; which, when the head is in its normal inoperative position contacts the inner edge, that is, the adjacent edge of plunger 12. At its rearward end the body 7 of head 5 is provided With-an extension 7a' having an arcuate .tor- Ward edge Which is curved on .the radius ot the" coin' used With the particular slide or plunger selected. I have illustrated'iny machine as provided with iive coiny slides Y or plungers which I have designated 12, 12?), 120,

12d and12e, these slides being adapted for reception of a 50e piece, a-'25tpiecc, a dime, a nickel, and a telephone slug, respectively.

lnjFigures 5. and 6 Iliave illustrated the coin slide or plunger for use with a25 piece, and associated parts. The operating head 5 is provided, at the other rear cornerthereoi'i, with an upturned tab 18 which is connected by pin andV slot' connections 191tothe upper end of the lever 20, the upper arm 21 of which extends through a slot 22through plate 3. As more clearlyshovvn in Figure 3, this lever comprises a body of substantially U-shape and an upper arm 21 extending from the upper end of this `body and the lower arm 23 extendingl downwardly from body 20a ot the Body 20o'J oi'.l the lever is pivoted intermediate in theni at 24, on a suitable support or Vbracket 25, suitably secured to back Wall 1b ofthe casing.

Five coinreceiving tubes 26, 27, 28, 29, and 30,- are disposed vertically in casing 1, the upper ends of these tubes being tightly secured through aligned openings in plate 3.

The tubes 26 to 30 are adapted to receive .half dollars, quarters, dimes, Ynickels and telephone slugs, respectively. Referring more particularly to Figures 1 and 8, a plate31 is Welded lor otherwise suitably secured on the l'oWer end of each of the tubes, with the exception of tubes 26. This plate is provided, at each side thereof, with a'channel guide element formed by bending the plate downwardly and then inwardly. A dispensing member 32 is slidably mounted in each plate and is provided, in the ends thereoic adjacent` the tube, With a recess for reception of the coin or coins to be dis aensed.

The recessed or relative thin portion 32a of the dispensing-plate normally extends bev`heath the adjacent coin tube sothatthe loivermost coin of the stack in suoli tube is disposed in the recess 33. This recess is of :arcuate shape, corresponding in radius to the radius oi the coin to be received therein.

leaf spring bearing against the lower portion of pin 34 and urging the dispensing plate or slide 32 away from the associated coin tube so as to normally hold it in inoperative position. When the dispensing slide is in inoperative position the end thereof remote from pin 34 is substantially coincident with a short discharge tube 38 secured through the bot- 'toni Wall ofcasing 1, this tube being otfset relative tothe associated coin tube. i

`When in this position, the slide'32 leaves thev tube 38 unobstructed so that a coin delivered thereto can pass to the tube 38 into a suitable receptacle 39 secured to'tlie under face of the bottoni of 'the casing. I have shown a receptacle, in th-e'forni of a cup, for each of the coin discharge tubes, as Well as the slug discharge tube, though this is not essentialand a suitable trough or other structure common to all `of the tubes may be used if desired.

-Reterring more particularly to Figures 3 and 4, the lower arm 23 of lever 20 associated with plunger 12 is connected, by pin and slot connections (Figure 1) 40, to a link 41 slidlable through a guide bracket 42 suitably secured to the upper tace of the bottom ot the casing 1. .This link is secured, at 43, to a bracket 44 which is secured to dispensing slides 32 adjacent coin tube 27. T heleaf spring 36 acts, through the dispensing slide 32`and links 41, to liold the operating` head 5 in its normal position adjacent the associated coin slide or plunger. In the same inanlner the operating head associated With the other coin slides or plungers are normally held in inoperative position, the position of the head for the 25g/s or quarter plunger being illustratedin such position in Figure 5. Each of the heads 5 is provided with a transversely extending slot 45 through-Which ex- 'fr-ont edge of this plate to an arcuate por-- @53 is shifted transversely of the slide toward opsubmitted in Figure 4.

erating head 5 with which the coin contacts., Continued movement of the slide causes: movement of head 5 in a direction away from edge 84 of plate 8l During the initial move-l ment of head 5 trip linger 8O is withdrawn from bet veen pawl 74 and plate 3, at which. time the pawl is moved into operative posi-- tion for engagementwith rack 79 thus pre-- vcntin withdrawal of slide 12?).y lNhen slidey i3?) has been moved into its innermost position, the coin 82 is' directly 'over the tube 27 and drops into' the tube by gravity. Ordi-- narily no` difficulty will be encountered in this discharge of the coin into the tube since the area of contact between the coin andhead.

5 and plate 8 is relatively small and the pres-- sure exerted on the head is comparatively slight. The'arcuate cut-out or recess 17 in. slide l2?) registers with the upper` end of the coin tube so that the coin,in its passage into the tube, passes downwardly through this.

recess.

rlhough ordinarily, noV diliculty should beu experienced in the discharge of the coin into the tube in the manner described, l contem-- platethe provision of any suitable means for ejecting the coin from between the operatingv head 5 and the edge of plate 8 into the tube. if this seems desirable.

Vflisthe slide l2 reaches its inner most position, operating head 5 actuates the dispensing slide of the associated tube, or more correct-- ly, of the tube or tubes, as the case maybe, controlled Vby the particular coin 4slide operated for dischargingV from t ieY machine a. telephone slug andthe correct change. Referring more particularly to Figure 4, if a half dollar be placed upon the slide 12 and` this slide be then moved into its innermost position, the lower end of lever 2O connected to link 4l will be moved toward `the left as This movement ofI link 4l will move the slide 32 of tubes 27, 28 and 30 toward the left so as to remove a ouarterfrom tube 27, two dimes from tube and a telephone slug from tube 30. `When the half dollar has Vreached its innermost' posit-ion, the slides referred to are disposed in their eXtreme position at the left with the. coins'and the slugs disposed in alignment with the discharge tribes 38.j At this time the coins in the tubes 27 and 28, and the slugs in the tube 30, are supported by the coins in the dispensing'slides 32 andthe slug in the dispensing slide beneath theslug tube# When the k iece drops into tube 26 head' is released and lever 2O is moved bythe spring 36 so to return this head to its normal position. rlhese springs also act to quickly return the dispensing slide 32 beneath the Y tulbes 27, 28 and 30 to inoperative position at fltubes. As a result, a quarter, two dimes, and

:a telephone slug are discharged through .the ttubes 38 into the cup 39. A person desiring ato telephone'is thus enabled to buy a slug :and to obtain theproper change without delay or any inconvenience to himself or any ioneelse. Referring "to igure l, it will be inoted that the upper face of thedispensing :slide 32 is, in each instance, spaced a short (distance away` from the lower end of the `fcoin or slug tube and the depth of the recess 33 of such dispensing plate, with the excep- :tion ,ofthel plate associated with tube 28, is :slightly less than the thickness of the coin "which this recess receives. The depth of the recess of plate 32 associated with tube 28 is :slightly less thantwice the thickness ofa .dime so that this plate receives two dimes fin superposed relation. lt will'thus beapparent that the weight of the coins and slugs remaining in thetube is supported by the coins or slugs in the dispensing plate 32 when :these plates have been moved into extreme position to the left, for causing discharge of the coins and slugs therefrom through the tube 38 in the manner described. l

`When a quarter is inserted into the inafchine, the rod 47 will be shifted toward the left so as to operate the ldispensing slide 32 iof the tube 28 and the dispensing slide 32 lof the tube 30.` Y

Due to the pin and slot connection 48 between link 4l and rods 47, the lever 2O associated with tube 26 will not be affected and, in the operation of: rod 47, the dispensing :slides for tubes 23 and 30 only will be'actuated. As a result, when a quarter is inserted linto the machine, two dimes and a slug will loe delivered.` Vhen a nickel is inserted into the machine the dispensing slide 32 of tube `33() will be actuated for discharging a slug.

Due to the'pin and slot connection between .arms and 73, and the fact that rods 47 `and 57 are not secured to dispensing slide 32 of tube 30, no other slide than the slides for dispensing or discharging a telephone slug `will be operated when a nickel is inserted.

ltnot infrequently happens that after a person obtains a slug, they are unable to obtain the connection desired in which place the slug is returned in a known manner. Under present conditions, it may frequently be necessary for the purchaser of the. slug to wait a considerable length of time before being ableto obtain the lrefund on the slug. As a result, itA frequently happens that. rather 1 than wait, the purchaser ofthe slug leaves the store without obtaining Varefund and, in the great majority of cases, the slug ii never used with aresulting loss to the pur- 'l l ceiving coinsvvhen the tubes havebeenli1led,
